Spreading Grevillea  |  

Grevillea humifusa

Status: Endangered on the EPBC Act list

The spreading grevillea is a prostrate shrub with a lignotuber, trailing stems to 3 m long and angular branchlets with long soft hairs. The grey-green leaves are 1.5Ð2 cm long and are ascending to spreading. The inflorescences are 2 cm long and occur at the end of the branches. The flowers are pink to red, and the style is pink to red with a yellow tip. The grooved, oblong fruit is 12Ð15 mm long and 3Ð4 mm wide (Stack & English 2003).

    They also exacerbate the threat of fire by increasing the fuel load.

    Fire Fire potential future Too frequent fire is a threat to the spreading frequency grevillea.

    However; grevillea seed generally has a short lifespan; and if fire recurred before adult plants could replenish the seed bank and re establish lignotuber reserves; the only known population could be seriously threatened.

    Grassy weeds can create a large fuel load; increasing the heat of fires.

    Fire o The species is impacted by fire either by being a post fire resprouter or seeder. i.e. fire is required for germination with fire killing the parent plant.
